Abstract:
The present disclosure relates to a differential including a differential case adapted to be rotated about an axis of rotation. The differential also includes a cross-shaft operatively coupled to the differential case such that the cross-shaft and the differential case rotate together about the axis of rotation; left and right clutch actuators having opposing inboard sides between which the cross-shaft is positioned; and left and right axle hubs positioned on opposite sides of the cross-shaft. A left clutch pack prevents relative rotation between the left clutch actuator and the left axle hub about the axis of rotation when a left clutch engagement pressure is applied to the left clutch pack and a right clutch pack prevents relative rotation between the right clutch actuator and the right axle hub about the axis of rotation when a right clutch engagement pressure is applied to the right clutch pack. A clutch pre-load spring applies pressure to both the left and right clutch packs without applying pressure to the left and right clutch actuators. The clutch pre-load spring is positioned inboard of the left and right clutch packs. Contact between the cross-shaft and a ramp surface at the inboard side of the left clutch actuator causes the left clutch engagement pressure to be applied to the left clutch pack, and contact between the cross-shaft and a ramp surface at the inboard side of the right clutch actuator causes the right clutch engagement pressure to be applied to the right clutch pack.
